Be itknown that I, -Josnrr MARKUS, a

citizen of the United fStates ot America, re-v agricultural machines andhas for its object to provide, in a manner as hereinafter set Jforth, amachine'ofsucl'i type having its body portion vcarrying a motor fordriving a machine and further having its body portion provided withmeans, in a manneras hereinaiiter set forth for adjustably anddetachably connecting therewith ground working implement such as abarrow, digger, or roller.

With the foregoing and other objects in l scribed and illustrated in theaccompanying drawing, whereinis shown an embodiment of the invention,but it is to be understood that changes, variations and modilicationscan be resorted to which come within the sco e of the claim hereuntoappended,

n the drawings wherein like reference characters denote correspondingparts throughout the several views: Figure 1 is a side elevationv of aself propelled agricultural machine in accordance with this invention.Fig. 2 is a top plan. Y Fig. 8 is a side elevation. Fig. is lan end viewof the plow share. Fie 5 is a side elevation. Fig. 6 is a top plan,oroken away, of one of the side bars of the machine body showing aharrow connected therewith.

. Referring to the drawings in detail the machine body comprises arectangular frame l, which is contracted at its forward end as at 2 andsaid contracted forward end has pivotally connected therewith, anarc-shape axle 3, having mounted thereon front wheels el.

platform 5 is secured to the frame 1 and mounted thereon is a :motor G,preferably oi an explosive type, and which has connected therewith aradiator 7 supported by the contracted forward portion 2 oli the trainel.

The frame l is constructed of an angloiron bent in a. rectangular mannerand with the ends of the bars inset tovprovide the contracted portion 2and the sides o the frame specification of Leiters raient. f

collar 9, having vextending through and i. `The wider portion of theframe l, near each terminus of each Side, has a laterally projectingcoupling member or keeper 8, for a purpose to be presently referred to.

vArranged against onel side of the wider portion of the frame 1,centrally of said side, is a vertically ,dis osed interiorly threadedanges 10, through which extend hold tast devices-1l, whereby said collar9 is i'xedly secured to the said side and engaging said threaded collaris a vertically disposed adiusting screw 12, having its upper end provided with a beveled gear 13 which meshes with the beveled gear lllcarried on the forn ward end of a longitudinally extending rate-ateaaan., i5, raie.:

shaft 15, the latter being mounted in bear l ing brackets 16, secured tothat Side of the frame which hasthe collar 9 Xed thereto. Therear end ofthe shaft l5 has a hand wheel 17 for 4the purpose of rotating the shafti5 when occasion so requires. l

Supported by the rear end 18 of the trame l, is a steering post 1.9,having its upper end provided with a hand wheel 20.v

The steering post extends below the frame l and carries on its lower enda sprocket wheel 2l, which engages with a sprocket chain 22, the latterhaving its ends connected to the axle 2, as at 23, and by such anarrangement the machine can be steered when desire Supported by the rearcud 18 of the frame 1 is a seat post 24. carrying a scat 25; the latteris arranged in proximity to the wheels l?, 20. l

Projecting rearwardly from the end 18ct the frame 1 is a rcctangula rtraine 26, which is of less width than the wider portion of the frame i,and which has its lower face, at itsvrear end. provided with bearings27,'

having rotatably mounted therein the rearl sprocket wheel 3ft by anendless chain-35.

The sprocket wheel 34 is carried by a m0*`= tor shaft 26; the latter isalso provided with a tlv wheel 37.

The roar end of the trame 26 is provided with coupling members 37a, foradjustably connecting the ground rollers to the body of the machine.

The coupling members 8 can be employedY ing member. The plow shareattaching member consists of a yoke-shape bar 38, provided with openingswhich are employed for adjustably connecting a plow standard to the barand the vertical arms of the said yoke-shape bar extend up through apair of coupling members 8 at one side of the wider 'portion of theframe l, as illustrated in Fig. l. The bar 38 has iixedly securedtherewith, by hold fast devices 40, an angle-iron all, formed with avertically dis posed collar 42, which is exteriorly threaded at Theadjusting screw 14 is adapted to engage with the threads 43 for thepurpose ot' vertically adjusting the bar 38 to position the plow shares44. By arranging the bar 38 in a manner as stated the shares arepositioned at one side of the machine frame.

The harrow adjusting member consists of a lateral bar and an inclinedbar 46, the latter having its forward end fxedly secured as' at 47, tothe outer end of the bar The inner ends of the bars 45, 46, are bentdownwardly at an angle as at 48 for the purpose of seating in a pair ofcoupling members 8, as clearly illustrated in Figs. 5 and 6, whereby thebarrow attaching member is coupled with the machine body.

The reference character 49 denotes a harrow, which has its forward endconnected with a bar 45, by flexible members 50 and furthermore has theinner corner of its forn ward end connected by a bar 45 and a rigidmember 5l. The rear inner corner of the barrow 49 is connected to theinner end of the bar 46 by a rigid member 52.

The motor shaft can be extended if desired so as to transmit power toother devices to operate them.

lVhat I claim is An agricultural machine comprising a shiftable bodyportion, means carried by the latter for propelling it, a pair of spacedcoupling members securedto the outer face of each side of said bodyrportion intermediate its ends, a vlongitudinally disposed and verticallyadjustable one-uiece yoke-'shaped bar having VVitsl vertical armsextending through a pair of sa'divcoupling members and its longitudinalarms having a row of openings to provide for adjustably connecting plowstandards therewith, and vertical adjusting means for said yoke bar, andmeans secured to the outer face of the longitudinal arm and projectinginwardly from the top edge of said bar and engaged by said adjustingmeans,v whereby said bar can be vertically adjusted. l

In testimony whereof I ax my signature in presence of a witness.`
